Well I went out to do a film of our local water tower and as I sent my Mac air 2 up to 200 ft it took off straight up until it disappeared. I tried all the controls to reduce height but no response from the drone. I hit the home button on the remote but still nothing. As I was about to give up I heard my drone close by and turned and saw it behind me above a tree about 100 ft high. I took control of it and landed it. Scared the life out of me, I saw $1000 flash before my eyes. I’m going to do a bunch of test flights before I try the water tower again.
